The events that led to us didn't come about purely through an environment that supports life. There was a set of geological and astronomical events that also fortuitously occurred to catapult mammals and eventually primates forward.


I kinda reject this kind of thinking. The video assumes that intelligent life HAD TO have exactly those conditions to arrive, and I think that is not a good assumption. There could be thousands of scenarios which would have lead to higher intelligence on this planet eventually.

My point is merely this, I have yet to find a reason to assume that high intelligence is an abnormality that arises from evolution. It seems to be a trait just like everything else. Right conditions and it can appear.

What might be true that there are cataclysmic events often enough that IF intelligence arises on other planets it might be always wiped out because of astronomical catastrophies. But even THAT is just speculation. Another scenario is that any "intelligent" civilization always end up killing itself. Dinosaurus roamed the globe for hundreds of millions of years without problem yet in a few thousand years humanity has almost humped the planet to oblivion.

Yes. There are a lot of potential ways where intelligent life could come about.

About civilizations destroying themselves, that's another thing to add to the list. I think our long term survival is less than 50%. Not because I have a negative view of people; I think people are generally decent. But as technology continues to advance, having 99.9% of the world being benevolent or at least not dangerous, and 0.01% of the world being radical would be all it takes to cause a domino effect that either destroys the world or at least most of it. The more powerful we get, the less room there is for error. Take North Korea. It makes up less than 1% of the world population, and of that population, less than 1% consist of military elite... and that is all it takes. And this is only 2017. Technology is going to keep marching forward.

Once upon a time we thought 2 superpowers having nukes was a big deal. In another 100 years that will be kid stuff. This is why I want all nuclear, chemical, biological, and pulse weapons banned and the world to phase into a single federal government, but that is asking for a lot too quickly because technology is now advancing at a much faster rate than sociopolitical development.

So yeah, unfortunately we are in a bad position imo.

We've been always on the brink..
That's nothing new. And that's what I'm talking about. There are many ways for species and even whole planets with all their species to die, and the only way to avoid becoming extinct EVENTUALLY is - as a species - to become so powerful that all possible disasters can be avoided or countered; all except self-destruction, that is.

Nah. Not true. As you can see in the first gif, the Poles around Cracow had anti-Black Death powers. If you can survive eating 3 week old perogis through childhood you are basically immune to biohazard. The only way to take them down is with a wooden stake to the heart.

But really, none of those came close to wiping people out. The American Native small pox epidemic was way, way worse than the Black Death and it still didn't wipe out ALL of the indigenous. The survivors were more resistant.

Doesn't change the point, though. The Neanderthalers have become extinct as well (and some other subspecies, too). Our survival as a species has always been in danger, and it is STILL in danger, and the lesser the danger of "natural" disasters, the higher the danger of self-destruction.

It won't take that long anymore, for example, when we will be able to destroy meteors of the sort that hit us 65 mio years ago, before they hit - but of course the destructive powers to to that can be used against us as well. The same is true for the ability to exterminate plagues or find cures for diseases.

Abuse/misuse is always possible - and might actually be a distinct hurdle to overcome.

Neanderthals went extinct (if you could call it that) not just through competition but because they were interbredable with other humans. Neanderthal DNA is still around today in all of us and it still isn't 100% certain that they don't still exist in remote cold areas but with a different morphology than from 100,000 years ago. Neanderthals are of course scientifically human. Modern humans are about 97% homosapien on average. You'd have to go to subhara Africa to find somebody 100% homosapien.

If you think about a prehistoric Earth, there is probably only going to be one species of human that emerges. People traded but they also fought over hunting ground back then and wouldn't have had much rule of law or "rights" outside of their tribe.

In reality, the reasons why the Neanderthalers wet extinct, are unknown (as so many things), and the "reasons" are only assumptions (it COULD be the reasons why). For example, there had been the theory that they would  have breastfeeded thei children longer than the other human species and for that reason a lower birthrate - but a couple of years ago they could check breastfeeding time by teeth analyzing and found the Neanderthaler in question had been 7 months breastfed and 7 more months breastfed plus additional food, and considering the chimpanzees are breastfeeding for up to 5 years, it was a pretty normal time.

There is one fact: differences in DNA between different Neanderthaler finds are very low, which means there probably has been too much interbreeding within the clans (which may be a reason that some tried their luck with cousins.

an article about how dolphins can recognize themselves in the mirror earlier than humans can.
https://www.nytimes.com/2018/01/10/science/dolphins-self-recognition.html

If you study dolphins you'll begin to understand they have a social intelligence that approaches humans.  They can sense each other's moods and act accordingly, they have a sense of 'ownership' in regards to objects, they play just like social primates - both as children and adults, they have a vocalization capability that exceeds humans (seven octaves), and they do cooperative hunting.  Most importantly, dolphins take turns doing baby-sitting duties, which indicates they're on the verge of eusociality (which is when animals become differentiated within a group).

Why is that important?  Cetaceans split with the other mammals about 50 million years ago.  As with the octopus example, it shows that greater intelligence is a trend that can occur in any group of animals.

Physics of life

Complexity in life might not be just a random coincidence, the laws of physics might demand it. Great video, and if this is true, then intelligent life is also more common that we might have thought.

That's all pretty bread & butter.

The original videos deal more with achieving intelligent life within the span of the current cosmic timeframe, not so much algae blooms or microbes.

(people have only talked about the 1st video but the 2nd talks about the regularity of extinction events)

And that's all only about recognizable life and/or intelligence.
